Code of Federal Regulations Title 20. Employees' Benefits § 20.10.813 If OWCP reduces a fee, may a provider bill the claimant for the balance?

(a) Where a provider's fee for a particular service or procedure is lower to the general public than as provided by the schedule of maximum allowable charges, the provider shall bill at the lower rate. A fee for a particular service or procedure which is higher than the provider's fee to the general public for that same service or procedure will be considered a charge “substantially in excess of such provider's customary charges” for the purposes of § 10.815(d).

(b) A provider whose fee for service is partially paid by OWCP as the result of the application of the schedule of maximum allowable charges and who collects or attempts to collect from the employee, either directly or through a collection agent, any amount in excess of the charge allowed by OWCP, and who does not cease such action or make appropriate refund to the employee within 60 days of the date of the decision of OWCP, shall be subject to the exclusion procedures provided by § 10.815(h).
